ATI AD202JYATI

The AD202JYATI is a high-voltage isolation amplifier designed for a wide range of applications, capable of measuring, processing, or transmitting input signals in a passive configuration. This isolation amplifier features a DIP package and provides signal and power isolation. The AD202JYATI employs internal transformer coupling to achieve complete galvanic isolation between the input and output stages. The amplifier requires no external DC-DC converter, enabling designers to minimize necessary circuit overhead, thereby reducing overall design costs and component costs. Powered directly from a 15V DC supply, the AD202JYATI offers compact size, high accuracy, low power consumption, wide bandwidth, excellent performance, flexible input configuration, and power isolation. The AD202JYATI uses amplitude modulation technology to achieve transformer coupling from signal to DC. The device also incorporates an uncommitted input op-amp and a power transformer that provides an isolated power supply for the op-amp, modulator, and any external loads. The power transformer primary winding is driven by an internally generated 20kHz, 15V peak-to-peak square wave.
